"The Trinamool Congress government has become non-functional after being enmeshed in this (Saradha) scam," West Bengal Congress president Adhir Chowdhury alleged.
Chowdhury also saw an imminent split in the ruling party, saying "several leaders are trying to save their backs.
A senior leader's son a few days back made some comments which indicated that a spilt is only a matter of time".
He also reiterated his demand that Mamata Banerjee step down till the CBI gave her a clean chit.
